Not a fan of the PPE's on cummins, i highly recomend them to our customers for the duramax, but not really a fan for the cummins, the black maxx has my vote, but teh xrt and smarty get the job done also, ppe just not any super power gains and for tuning i think, but dont get me wrong, would not put anything else besides efi live on a duramax. They are a very good company though.
